Your browser does not allow reading or saving the encryption keys, as the IndexedDB seems to be disabled. Without the IndexedDB, OpenCopy can't work.
There was an error accessing the IndexedDB. Possible fixed are to change the browser, delete all stored website data. Please try again later.
You seem to have OpenCopy open in another tab while there was an update on the server. Please reload this page and ignore all error messages coming in.
